However, as Sabu Singh, 40, was also charged with the indictable offence of perverting the course of justice, the Magistrate Caroline Campbell sent the case to York Crown Court for trial on November 6.

Sukhdev Singh, 36, was also charged with possessing cannabis.

Prosecutor Kim Coley added that due to the significant amount of cannabis plants recovered from the factory, all three of the defendants should face trial at Crown Court.

Defence solicitor Andrew Vickers said his clients were 'fully aware' of the bail conditions that they should make no contact with the three witnesses.

Mrs Cook said: "You face serious charges and one is indictable only so it will be sent to the Crown Court."

162 plants were found on the lower floor of S&R Motors on Harrogate Road, Ferrensby, on Tuesday, April 28 when a local officer became suspicious about the site.

The hidden operation was discovered after the officer went to investigate and found the plants, along with equipment commonly used in the production of cannabis.
